How warm was Europe in 2025? 🔍 It was the third‑warmest year on record for Europe, with an average temperature of 10.41°C, 1.17°C above the 1991–2020 average and 0.30°C below the record year of 2024. #CopernicusClimate #GCH2025

Global mean temperature 2025: 1.44 ± 0.13 °C above the 1850-1900 average, based on a synthesis of eight international datasets.
2025 was the second or third warmest year on record. 2024 remains the warmest.
That makes the past 3 years are the 3 warmest years on record.

Have you seen our overview of the 2025 wildfire season?
Data from #CopernicusAtmosphere shows how record emissions in Europe and major wildfires in the Northern Hemisphere sent smoke and pollution far beyond the fire zones, degrading air quality across continents.

Unusual amounts of snow for the Netherlands the last few days. Here’s an animation based on measurements of ~300 observers.
❄️ Het sneeuwdek van afgelopen week.
📏 Elke dag om 9u (in de winter en 10u in de zomer) meten de ruim 300 vrijwillige neerslagwaarnemers van het KNMI hoeveel neerslag er is gevallen, deze dagen is dat sneeuw. Dankzij hun metingen krijgen we beter inzicht in de verdeling van de neerslag in Nederland.

Permafrost (frozen ground) is the backbone of northern ecosystems. Watch this field video for a visual demonstration of what happens when we lose that permafrost to thaw.

And now we know that the volume of #Arctic sea ice also dropped to a record low in October (zacklabe.com/archive-2025/).
It's been a historic fall in the #Arctic, which is already a season of rapid climate change. Not good.

It seems boring but it is actually a REVOLUTION! SOFF is the hope that the huge gaps in our global observing system are filled.
At #COP30, the Systematic Observations Financing Facility (SOFF) – a UN Fund proudly co-created by WMO, @undp.org and @unep.org - will announce a first-of-its-kind instrument to help close this gap: The SOFF Impact Bond.

Just 2 more years at current rates. It is essentially impossible to avoid global temperature rise exceeding 1.5˚C.

Why did GHG emissions rise?
50% of the increase was from land-use change, primarily due to more fires during El Niño. We expect this to drop in 2025. LUC is also very uncertain.
All other main regions, except EU27, with rising emissions in 2024.
